i run a tbi tank on left side with tbi sender and 96 c3500 350 vortec spec intank pump no mods just clips in for my efi system needs .

then my pass side tank i just use a stock tbi tank / sender / pump and a toggle switch in the dash to pump it over to the left tank . there is also a red light on the dash just under the radio that lights up when pumping so i dont forget and it cant pump with key off only running .

i tee'd in to the filler neck vent hose and it dumps in the tank just fine . this let me keep it simple stupid and no expensive parts / valves or what not .
